Out of all the good available free agents this off-season, there are more big men than anything. Sure Lebron James and Dwyane Wade are probably the two biggest free agent names, but after that the best guys out there are all bigs.
If the Nets draft Johnson it would then put them in a situation to pursue one of the big guys out there.
Names that they would pursue would probably include: Chris Bosh, Amare Stoudemire, Carlos Boozer, and David Lee.
Out of these names the most likely names to land in New Jersey would probably be Amare or Carlos Boozer.
The Nets really like Derrick Favors and his NBA player comparison is Amare Stoudemire, thus, the Nets would love to land him.
Unfortunately for them, I believe Amare will most likely go team up with Wade in Miami, but the acquiring of Boozer would be far from a lose.
In fact, Boozer would seem to fit in a little better to the Nets team, seeing how Lopez is the low post guy and Boozer has the ability to step out and hit a very reliable jump shot.
No one knows for sure who the Nets would land in the free agency with this scenario, but it's almost a guarantee that they would draw in one of the good free agent big men so they would be sitting pretty.
